Caverta 100 Pill belongs to the class of drugs known as PDE5 inhibitors. The medicine works well because it lessens the flow of blood to the penis. When a man is excited sexually, this increases blood flow to his penis, which eventually results in an erection. In order for this medicine to have its desired effect of producing an erection, the user must first be sexually aroused. Nevertheless, it won't work unless you take it 30 minutes before becoming sexual.
The majority of unwanted effects from taking medication often diminish when the body adjusts to the substance. If you are concerned that your symptoms aren't improving, make an appointment with your primary care doctor.
